New Firmware Installation WARNG: Interrupting the download process before it is completed will result in lost EEPROM data. In the event that the download is prematurely terminated, contact the factory. To download new software to the TPU-2000R: If desired, save all settings to a disk as described in Section 12. On your computer s hard drive, create a directory called C:\FPI. Copy files from the FPI diskette (FPI.exe) and the SAF diskette (filename.abs) to the C:\FPI drive. Remember the filename from the SAF diskette as it will be needed later. Connect the TPU-2000R to the computer via the serial port on the front panel of the unit with a null modem cable. Ensure that the communications settings of the computer com port and the settings of the TPU-2000R are both set to 9600, 8, N, 1. At the C:\FPI prompt, type FPI At the Monitor Type? prompt, select the appropriate monitor (color or black and white) and press <CR>. After the ABB description screen, the Communication Options screen appears. Use the spacebar to change the com settings or accept the default settings by scrolling through the screen with the <CR> key. If all com settings are correct, the Successful Connection To... screen appears. Press <CR> to continue. The next screen to appear will be the Main Menu.

Built-In Testing The TPU-2000R continuously checks itself for proper functioning. # Self-Test Status The TPU-2000R provides continuous self-testing of its power supply voltages, memory elements, digital signal processor and its program execution. In the event of a system failure, the protective functions are disabled and the Self-Check Alarm contacts are actuated. Except for a processor stalled condition, review the PASS/FAIL status of these self-test elements by using the man-machine interface (MMI). Normal status is indicated by a green TPU STATUS light (LED) and system failure is indicated by a red TPU STATUS light (or by the green TPU STATUS light not being lit in the case of a loss of control power). If the green light is flashing, refer to the Operations Menu in Section 9. Self-Test Failures are recorded as a number in the Operations Record. The binary bit pattern of this number indicates the Self-Test Failure or Editor Access Status involved. The 1 s in the bit pattern indicate where a failure has occurred. Count from the right of the bit pattern (starting with zero) to the position where a 1 occurs. Compare that bit position with Table 4-1 to reveal the failure. See the following examples for further explanation. If the self-test fails, the TPU-2000R is no longer providing protection. Replace the unit as soon as possible. Table 4-1.

Example of a Self-Test Failure Value : 256 has a binary bit pattern of 0000000100000000 (bit order 15...0) The 1 is in bit position 8 as you count from the right. This bit position correlates to DSP ROM failure. Example of an Editor Access Value : 145 has a binary bit pattern of 0000000010010001 (bit order 15...0) The 1 s in this bit pattern have the following bit positions and corresponding Editor Access Status: Bit 0 : Interrupt logging bit (Ignore this bit because it will always be set in this example.) Bit 4 : Front communications port initiated the editor access and change. Bit 7 : Real-time clock settings were changed. TPU-2000R Settings Tables Diagnostics Three copies of each settings table are stored in nonvolatile memory, preventing data loss during control power cycling. When you finish editing any settings table, the changed table s data is transferred from a temporary edit buffer into three separate locations in nonvolatile memory. A background diagnostics task continuously runs a checksum on each copy of the settings tables to verify data consistency. If an invalid copy is detected, the diagnostic task attempts self-correction by transferring a valid copy to the invalid copy location. If this is unsuccessful, the task marks the copy as unusable and switches to the next available copy. When the TPU-2000R detects that all three copies of a settings table are not valid, the diagnostic task adds a selfdiagnostic error in the Operations Record, drops the self-check alarm, and disables all protective functions. In addition, the Self Test display under the MMI Test Menu shows the current status (PASS or FAIL) for all memory devices. 4-10 Relay Design and Specifications
Man-Machine Interface (MMI) C E The man-machine interface (MMI) on the front panel consists of a four-line liquid crystal display (LCD) with twenty characters per line, six push-buttons (keys) and thirteen LED targets. Press the Enter <E> key to access the Main Menu. Use the up and down arrow keys to move through the various menus and to change the character value when you enter the alphanumeric password. Use the Enter <E> key to select the desired menu or desired value when you change settings. Use the left and right arrow keys to decrease and increase, respectively, setting values or record numbers. You can also use them to move from left to right within the password string. Hold down or repeatedly press the arrow keys to change the setting value. Figure 5-1. MMI Access Panel Use the clear <C> key to return to the previous menu.
